The new filing is a harsh attack on the company designed to undermine their standing in the courts ahead of major trials that will begin January. BP has proposed an $8.7 billion settlement with thousands of Gulf Coast residents and business that would pay out claims to those affected by the spill but would not hold them liable for the accident. The federal government is not a party to that settlement and is worried that the claims BP makes in it could undermine their own civil and criminal cases against the company. This new filing (which you can read online) is meant to dismantle BP's legal arguments and ask that a judge refrain from making legal findings of fact until their own cases go to trial next year. The state of Alabama (which is also not part of the early settlement) also weighed in, accusing the company of wasting time and money trying to stop the spill with a method they knew would likely fail.
